How can I get my transmission temperature on the Torque Pro App ?

2006, LS2 Coupe, with Manual Trans.

Tough to do since the manual doesn't have a temp sensor that I am aware of.

trade it for an auto transmission

Try Track Addict HD, it's got a slightly different list of PIDs available.

I don't think the manual trans has a sensor either...and no program can get a temp reading of something unless there is a sensor hooked up to the system. The auto trans has one.

I bought a dashlogic device (this - https://www.corvetteforum.com/forums...-corvette.html ), and it is showing "trans temp" for my 2011 GS manual transmission.

I set it to monitor oil temp and transmission temp on the same screen, and this morning, the oil temp got to 159 degrees, and the transmission temp got to 121 degrees. Both started out at 64 degrees when I fired up the car to leave, it was parked outside.

This was about a 20 mile drive in the dark, mostly interstate driving, with the outside temp on the HVAC unit was 63 degrees.
